MedKoo CAT#: 522397

CAS#: 1448723-60-1

Description: UM729 is an enhancer of AhR antagonists. UM-729 enhances the self-renewal of human hematopoietic stem cells in vitro. UM729 does not inhibit the aryl hydrocarbon receptor (AhR) pathway, but has been shown to collaborate with AHR antagonists in preventing differentiation of acute myeloid leukemia (AML) cells in culture. UM729 was originally discovered in a screen of compounds capable of promoting human CD34+ cell expansion. UM-729 may be used for the enhancement of human HSC self-renewal in culture, and for the maintenance of human leukemia stem cell (LSC) activity in culture.

Preparing Stock Solutions

The following data is based on the product molecular weight 367.45 Batch specific molecular weights may vary from batch to batch due to the degree of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 1.15 mL 5.76 mL 11.51 mL
5 mM 0.23 mL 1.15 mL 2.3 mL
10 mM 0.12 mL 0.58 mL 1.15 mL
50 mM 0.02 mL 0.12 mL 0.23 mL
